Abstract

PROBLEM TO BE SOLVED: To prevent pulling-out force from being fluctuated by providing pulling-out openings at the central part of the top board of the cap by two steps and providing a radially cross-shaped slit made from a pulling-out hole provided on the top board of the upper step ranging from the top board of the upper step to the top board of the lower step on a cap with a small lid of a wet tissue container. SOLUTION: In a cap with a small lid mounted by biting or screwing on a wide opening neck part of a cylindrical container main body made of a plastic, a pulling-out opening part 100 of a wet tissue is stood at the central position of a cap top board 11 by a shape of two steps and a pulling-out hole 130 is provided at the central position of the top board 111 of the upper step 110. A radially cross-shaped slit 140 made from this pulling-out hole 130 is provided from the top board 111 of the upper step 110 to the top board 121 of the lower step 120. In addition, a design is performed in such a way that a relation T1 > T2 >=T3 >=T4 >=0.8mm is helt among thicknesses T1 , T2 , T3 and T4 of the top board 11, the top board 121 of the lower step 120, the peripheral wall 112 of the upper step 110 and the top board 111 of the upper step 110.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cap with a small lid having an outlet for a wet tissue used for a wet tissue container.

[0002]

2. Description of the Related Art Wet tissue containers are usually 70
Or 150 wet tissues are connected to each other and wound continuously into a roll, and stored in a plastic cylindrical container body. The plastic body having a wet-tissue outlet at the wide-mouth neck of the container body. With a cap with a small lid. Then, when using the wet tissue, the small lid of the cap was opened, and the wet tissue whose tip protruded was pulled out with a finger from the outlet of the wet tissue outlet, and the tip of the next wet tissue came out. Sometimes, the connection between the wet tissues is automatically cut off by the tightening force of the wet tissues in the take-out hole, and the wet tissues are separated and used one by one. In the conventional wet tissue container, the take-out opening of the wet tissue is provided with a take-out hole at the center position of the top plate of the cap on which the small lid is crowned, and a cross-shaped slit is provided radially from the take-out hole in the periphery. Were common.

[0003]

However, the conventional cap with a small lid of the above-mentioned wet tissue container has little flexibility around the wet tissue take-out hole, so that the wet tissue take-out force is inevitably uneven. Or the wet tissue was clogged in the take-out hole during take-out. In addition, when changing the thickness of the wet tissue to be accommodated, it is necessary to change the shape of the take-out hole and the slit. For this reason, there is a case in which a separate part such as silicone rubber having flexibility is fitted in the take-out hole of the wet tissue, but the number of manufacturing steps is increased and the manufacturing cost is inevitably increased.

The present invention has solved the above-mentioned problem of the conventional cap with a lid for a wet tissue container.
Flexibility without using separate parts in the take-out opening of the wet tissue, no unevenness in the take-out force of the wet tissue, and the wet tissue can be used as it is even if the thickness of the wet tissue is changed The present invention provides a cap with a small lid having a take-out opening.

[0005]

Means for Solving the Problems A first invention of the present invention is:
As shown in FIGS. 1A to 1C, in the cap with a small lid having an outlet for a wet tissue, the outlet (100) has a two-stage shape at the center position of the cap top plate (11). And the upper plate (110)

According to a third aspect of the present invention, as shown in FIGS. 1 (c) and 3, the take-out hole (130) is provided at the lower end of a cylindrical upper step hole (131) at the lower end of a truncated cone. Hole (13
The cap with a small lid according to the first invention or the second invention, characterized in that the upper end of 2) is connected by a curved surface.

[0008]

According to the present invention, as shown in FIGS. 1 (a) to 1 (c), a cap with a small lid having a wet tissue outlet is provided such that the outlet (100) is positioned at the center of the cap top plate (11). The upper plate (110) is provided with a take-out hole (130) at the center position of the top plate (111), and a cross slit (140) is radially formed from the take-out hole in the upper plate (111). Since the lower plate (120) is provided up to the top plate (121), the take-out hole and the take-out portion have appropriate flexibility, and in normal use, the take-out force of the wet tissue is not uneven, and Even if the paper thickness of the tissue is changed, it can be used as it is.

The cap top plate (1) shown in FIG.

_{Since the} cap outlet is manufactured so that the relational expression of ₄ ≧ 0.8 mm is satisfied, the outlet has appropriate flexibility for taking out the wet tissue. The above relational expressions have been obtained through repeated trial productions by the inventor.

As shown in FIG. 1 (c), a take-out hole (130) is formed by connecting the upper end of a truncated conical lower stage hole (132) to the lower end of a cylindrical upper stage hole (131) by a curved surface. Due to the shape, when the wet tissue is pulled out from the take-out hole of the cap, the wet tissue has an appropriate tightening force, and there is no fear that the wet tissue is caught in the mouth of the cap.

[0011]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A cap with a small lid according to the present invention is shown in FIG.
As shown in the figure, a take-out portion (100) of a wet tissue is located at the center of the top plate (11) on which the small lid (13) is crowned.
A plastic cylindrical container main body (20) for accommodating a wet tissue wound in a continuous roll and wound into a roll is used by being attached to the wide-mouth neck portion by means of an occlusion or screwing.

The above-mentioned outlet (100) is shown in FIG.
As shown in (a) to (c), the cap top plate (11)
Is formed in a two-stage shape at the center position of the top plate (110), and an extraction hole (130) is provided at the center position of the top plate (111) of the upper stage (110).
0) from the top plate to the top plate (121) of the lower stage (120)
It is provided up to.

The thickness (T ₁ ) of the cap top plate (11) shown in FIG. 1B and the thickness (T ₂ ) of the top plate (121) at the lower stage (120) of the outlet (100) are shown. And the upper row (1
Between the thickness of the peripheral wall (112) of 10) and (T ₃₎ upper top plate thickness (111) and _{(T 4), T 1>} T 2 ≧ T 3
The product specifications are designed so that the relational expression of ≧ T ₄ ≧ 0.8 mm is satisfied.

As shown in FIG. 3, the take-out hole (130) is connected to the lower end of the cylindrical upper step hole (131) at the upper end of the truncated conical lower step hole (132) by a curved surface (R). the shape, the diameter of the lower end of the lower bore (132) (D ₂ φ) is preferably to design the product specifications to 4mm larger than the diameter of the upper hole (D ₁ φ).

The cap with a small lid according to the present invention is manufactured by injection molding using polyethylene, polypropylene or the like.

Further, as shown in FIG. 2, the container body (20) usually has an engaging portion such as a bite or a screw with the cap on the outer surface of the mouth and neck, and is formed by hollow molding of polyethylene or polypropylene. It is a cylindrical wide-mouthed container.

[0017]

When the cap with a small lid according to the present invention is mounted on the wide-mouth neck of the container body containing the wet tissue, the wet-tissue take-out hole and the take-out opening have appropriate flexibility, so that the wet tissue can be used. When taking out, there is no unevenness in the taking-out force, and even if the paper thickness of the wet tissue is changed, it can be used without changing the shape of the taking-out hole.

For this reason, it is not necessary to correct the shape of the mold of the take-out hole or to use a separate flexible part for the take-out hole, and the manufacturing cost of the cap is reduced.
